I set up a sorority the other day with a female I got in the mail with my Aquabid boy and some Petco females. I specifically made sure to get all Veiltail females, and my receipt reflects that.

I noticed that there are two bubble nests in my sorority tank, whereas neither of my boys have even considered building a nest. The girls have been getting along wonderfully, though there is one for sure that is in charge. Some of my girls look a little plump. What's going on?
